My old PC died due to motherboard failure. The disk contents are valid and the BOINC (SETI) are accessible. My new PC (all new) is up and running, also went from Win XP to Win 7 64-bit. I have copied the "Documents and Settings\All Users\Application Data\BOINC" folder onto the new hard drive under "Libraries\Documents\My Documents\BOINC".

So what is the best way to get me up and running again? I have not downloaded or installed any BOINC Software. I think I was running the 6.10.60 version of BOINC when the PC failed.

Thank you for your prompt response. I suspected that was the solution, but since Windows 7 has new features regarding data mapping on the disk, I wanted to be sure. What you suggested worked perfectly. I'm also running much faster, old cpu was Intel E8400 dual core, new one is i5-2500K quad core.
